《矩阵与变换》是高中新课程的新增内容,是中学课程内容的延伸与拓展,在此专题中,矩阵中的概念和结论一般都是先通过具体的几何变换(几何直观)使学生获得感知的,因此,立足几何变换(几何直观)是研究二阶矩阵的基本出发点.当然,立足几何直观、利用变换思想也是处理一些数学问题的重要解题策略。 “Matrix and Transformation” is a new content of high school new curriculum, is an extension of secondary school curriculum content and expansion, in this topic, the concept and conclusion of the matrix are generally through specific geometric transformation (geometric intuition) to enable students to obtain Therefore, based on geometric transformation (geometric intuition) is the basic starting point for the study of second-order matrices.Of course, based on geometric intuition, the use of transformation is also an important problem-solving strategy for solving some mathematical problems.
